- Chess players reconstructing positions from screenshots
- Worth noticing
- Recognition can be corrected manually, and the interface flags uncertain squares before analysis.
Field notes
The interface accepts PNG, JPG, JPEG, or WEBP images up to 15 MB, then asks users to crop the 64 squares and choose board orientation. It warns that recognition is approximate, marks uncertain squares for review, and provides manual piece editing, FEN copying, and PGN exploration controls. Analysis is labeled Stockfish 19 Lite, with quick, balanced, and deep settings of 2, 5, and 12 seconds; the page says computation runs in the browser.
